Yeah, that looks broken.

Does this still happen with current squeeze kernels?  If so, please
try a 3.x.y kernel from unstable; the only packages from outside
squeeze that should be needed in order to do so aside from the kernel
image itself are initramfs-tools and linux-base.  If it fails, we can
get help from upstream, and if it succeeds, we can try some kernels
halfway between from http://snapshot.debian.org/ to find the fix and
try applying the same patch to squeeze.

Thanks for writing, and sorry for the slow response.

Sincerely,
Jonathan
